Ruby on Rails: “couldn't find file 'jquery-ui'”

Question

I\'ve just done a fresh install and was able to access the default rails page at localhost:3000, but when I installed the activeadmin gem I had a problem when accessing /admin/

Answer 1

If you are using later versions of jquery-ui-rails in my case jquery-ui-rails-5.0.0

I found out in the jquery-ui-rails-5.0.0 assets folder, that writing the following line into your application.css:

*= require jquery-ui

fetches all ui elements for your css, it simply calls:

*= require jquery-ui/all

and if you write the following into your application.js

//= require jquery-ui

it fetches most jquery js files, with exception of some specific datepickers, there is no #all method for jquery in application.js, in most cases these would do, but if not, then you can add the rest diretcly into applications.js e.g

//=require jquery-ui/datepicker-ru

So in summary to use all ui for both css and js

*= require jquery-ui
//= require jquery-ui
